3 Claims.

This invention relates to double thick welting.

One object of the invention is to make a welt of this type in which thestock may be used with a minimum of waste and of manufacturingoperations.

When the welt is to be made of leather, the strips of which it is madeare cemented together with their flesh faces in contact. This permitssecure attachment of these parts together without the necessity ofroughing the surfaces, which not only requires an additional operation,but also results in loss of stock material.

For a complete understanding of this invention, reference may be had tothe accompanying drawing in which Figure 1 is a perspective view of ablank from which the welt may be made, showing the cut by which it isdivided into two strips which are superposed on each other to form thewelt.

Figure 2 is a perspective view showing the two strips of Figure 1cemented together.

Figure 3 is a transverse sectional view through the strips of Figure 2showing the inner margin of the wider strip being bent down to completethe welt.

Figure 4 is a detail sectional view taken through the outer edge portionof a shoe showing the welt of Figure 3 employed therein.

Referring to Figure 1 of the drawings, a substantially rectangular blankI, which may well be of leather, is cut longitudinally along a diagonalat 2 to form a pair of strips 3 and 4. Either before or after thiscutting of the blank into two strips, the grain face of the portion 4 isprovided with a longitudinal groove 5. This may well extendsubstantially a third of the thickness of the blank and is intended torelieve this face of the material to facilitate bending in the furthermanufacture or attachment of the welt, as will later appear.

The strip 4 is substantially wider than the strip 3 and terminates inone beveled side edge 2. The narrower strip 3 also has a similarlybeveled edge 6. The narrower strip 3 is reversed so as to present itswider flesh face 1 upwardly, and this flesh face I is then cemented tothe flesh face 8, which is the narrower face of the wider strip 4.

The perpendicular edge faces 9 and ll) of the strips ll and 3 may wellbe arranged in alinement with each other, and this brings the beveledface 6 of the lower narrower strip substantially parallel to the beveledface 2 of the strip 4, being outwardly offset therefrom so as to bringthe inner adjacent edge of the face I substantially beneath Figure 2.

Either as a preliminary operation, or when the welt is beingincorporated in a shoe, the widthwise portion of the strip 4 from aboutthe center of the groove 5 to the beveled edge is then bent downwardlyso as to bring the beveled edge 5 substantially into the plane of thelower narrower face 15 of the narrower strip 3. In Figure 3 this bendingoperation is shown as preliminary and performed between the flat facedroll I I and the roll 12, which has a pair of tapered face portions I 3and M for engagement with the portion of the strip 4 which extendsbeyond the beveled edge 6 of the narrower strip and a portion of thesurface formed by the groove 5. The cutting of this groove 5 relievesthe material of the welt strip locally so that it may be bent readilyinto the desired position shown in Figure 3. This brings the extendedportion of the wider strip 4 substantially opposite to the beveled face6 of the narrower strip, defining therewith a longitudinally extendingnotch or groove l1 within which may lie the inseam stitching l8 (seeFigure 4), which is employed to secure the welt to the upper materialsI!) and 20, and to the inseamreceiving rib 2| of a welt innersole 22.Not only does the formation of the groove 5 relieve the flesh face ofthat portion of the strip which is to be bent to final form, but it alsotends to shape the surface of the welt which engages the upper member l9to the general ogee contour of the upper opposite to the innersole sothat tight engagement of the welt against the upper is insured.

It will be noted that the flesh faces of the two strips are cementedtogether, this avoiding the necessity of roughing the surfaces whichwould be required were one or more grain faces to be cemented. This notonly avoids the roughing operation, but it avoids the waste of weltmaterial which would be produced by the roughing operation. The onlywaste material formed in the production of this welt is the small amountremoved in forming the groove 5.

In the finished shoe the grain face of the strip 4 is presented upwardlywhere it is exposed in the finished shoe, the grain face being capableof receiving a better finish than can the flesh face. The welt issecured to the outersole 25 by the usual outersole stitching 26.

It will also be noted that the welt may be made from a single blankstrip of rectangular cross section so that it may be readily formed upfrom the leather stock.

2. A welt comprising a pair of superposed leather strips cementedtogether in face to face relation with their flesh faces in mutualcontact,

the upper and wider of said strips extend-ingzinwardly and downwardlybeyond the adjacentedge of the lower and narrower strip and definingwith said adjacent edge an inseam-receiving groove,

said upper strip having a groove in the grain face of said inwardly anddownwardly extending portion.

in its upper face.

3. A welt comprising a pair of superposed strips cemented together inface to face relation, each strip having its inner edge face beveleddownwardly and outwardly, the upper and wider of said strips extendinginwardly and downwardly beyond the edge of the lower narrower strip andwith its beveled edge substantially in the plane of the lower face ofsaid narrower strip, said inwardly and downwardly extending portiondefining Wfth'the adjacent edgeof said narrower strip aninseam-receiving groove and having a groove Eli/[IL R.
